BUGKLES AND THE METHOD OF PRODUCING THE SAME Filed Sept. 3, 1943.

INVENTOR v Qrro 62 /55 BY ATT RNEY' Patented Sept. 10, 1946 UNITED STATES PATENT OFFICE BUCKLE AND THE METHOD OF PRODUCING THE SAME Otto Gries, New Rochelle, N. Y., assignor to Gries Reproducer Corporation, a corporation of New York Application September 3, 1943, Serial No. 501,197 (Cl. 293) 2 Claims.

This invention relates to buckles, particularly of the type in the form of loop shaped or ring like bodies having pivoted hasps therein. More particularly, theinvention relates to a method of constructing buckles of the kind described in such manner as to materially reduce the cost of the product by simplifying the method of producing the separate parts thereof, and in assembling the parts and at the same time, producing a buckl of strong and durable construction. The novel features of the invention will be best understood from the following descriptions when taken together with the accompanying drawing, in which certain embodiments of the invention are disclosed, and in which the separate parts are designated by suitable reference characters in each of the views; and in which:

Fig. 1 is a plan view of the buckle body in its blanked form. I

Fig. 2 is a cross section on the line 2-2 of Fig. 1.

Fig. 3 is a plan view of a hasp, with part of the construction in section.

Fig. 4 is an end view of the hasp; and

Fig. 5 is a diagrammatic view, illustrating the method of coupling the hasp with the buckle body.

In Figs. 1 and 2 of the drawing is illustrated at ID, the buckle body or blank which is in the form of a loop defined by a round bar end I l, a wider or flattened bar end l2, and outwardly bowed sides 13. In other words, in forming the body Hi, this body is formed with bowed sides l3 so as to space opposed and inwardly projecting conical centers H a sufiicient distance apart to freely receive a hasp l5 or the cross bar l6 thereof.

The hasp I5 is shown in detail in Figs. 3 and 4 and on the cross bar are a number of prongs l1, two illustrated in the construction shown. The ends of the bar l6 have conical center recesses I8 in which the conical centers M are adapted to seat.

It will be apparent that the spacing between the conical centers M will be such as to freely receive th bar l6 of the hasp. In producing the resulting buckle, the parts are arranged with the hasp l5 in alinement with the centers I4 in the manner illustrated in Fig.5 of the drawing, and the bulged sides l3 of the buckle are forced inwardly by two anvils l9 and 20 so as to square the sides 13 and seat the centers M in the recesses l8 of the hasps.

In the above re-shaping operation of the body ID, that is to say, in removing the bulge from the sides, the movement of the anvils will be controlled to check this operation at a point where the conical centers II will fit snugly or in fact,

tightly in the sockets or recesses I8. The slight spring back which will prevail in this operation will free the conical centers l4 sufficiently in the sockets I8 to provide free rotation of the hasp on the pivot centers M.

The buckle body or loop NJ, as well as the hasp ii are both formed from die castings and without the necessity of having to use any complicated cores, and further without the necessity of machining operations. The recess or sockets l8 will be formed in the hasp by the use of conical end pins arranged on the parting line of the dies, and these pins will free the casting from the dies in the separation thereof and by separating these pins, the hasp may readily be discharged from the casting machine.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is:

' 1. The method of producing buckles of the class described, comprising forming independent die castings, one in the form of a four-sided ring-like body having opposed outwardly bowed sides with inwardly projecting and alined conical pivot parts on said bowed sides, the other casting comprising a pronged rod having a conical socket in the ends thereof, forming said rod of a length less than the spacing between the pivot parts of said bowed sides, arranging said rod between and with the socket ends of the rod in alinement with and adjacent the projecting pivot parts of said bowed sides, and then moving the bowed sides toward each other into parallel relationship to arrange the projecting pivot parts snugly but freely within the sockets of said rod in pivotally coupling and permanently retaining the rod in said body.

2. In buckles, the combination with a hasp, comprising a cross-bar having conical recesses in the ends thereof, said bar being of a length equal to the normal spacing between inner surfaces of opposed walls of a buckle body in which the bar is adapted to be arranged, of a die cast buckle body blank, said blank having opposed walls curved outwardly, inner surfaces of the outwardly curved walls of said blank having centrally thereof inwardly projecting integral conical pivot parts
